"Many will be confronted by the spirits of devils personating beloved relatives or friends and declaring the most dangerous heresies. These visitants will appeal to our tenderest sympathies and will work miracles to sustain their pretensions. We must be prepared to withstand them with the Bible truth that the dead know not anything and that they who thus appear are the spirits of devils. GC 560.1"
"And no marvel; for Satan himself is transformed into an angel of light."
EGW's description of spirits of devils personating loved ones aligns with the concept of Satan transforming himself into an angel of light, as described in 2 Corinthians 11:14. Both passages warn about deceptive appearances.
"Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;"
Both passages discuss the deception of spirits and doctrines of devils, particularly in the context of the 'latter times' or end times. EGW's warning about 'spirits of devils' aligns with 1 Timothy 4:1's warning about 'seducing spirits, and doctrines of devils.'
"the earth.” Revelation 3:10 . All whose faith is not firmly established upon the word of God will be deceived and overcome. Satan “works with all deceivableness of unrighteousness” to gain control of the children of men, and his deceptions will continually increase. But he can gain his object only as men voluntarily yield to his temptations. Those who are earnestly seeking a knowledge of the truth and are striving to purify their souls through obedience, thus doing what they can to prepare for the conflict, will find, in the God of truth, a sure defense. “Because thou hast kept the word of My patience, I also will keep thee” ( verse 10 ), is the Saviour's promise. He would sooner send every angel out of heaven to protect His people than leave one soul that trusts in Him to be overcome by Satan. GC 560.2"
"Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth."
Ellen White directly references Revelation 3:10 in this passage.
"The prophet Isaiah brings to view the fearful deception which will come upon the wicked, causing them to count themselves secure from the judgments of God: “We have made a covenant with death, and with hell are we at agreement; when the overflowing scourge shall pass through, it shall not come unto us: for we have made lies our refuge, and under falsehood have we hid ourselves.” Isaiah 28:15 . In the class here described are included those who in their stubborn impenitence comfort themselves with the assurance that there is to be no punishment for the sinner; that all mankind, it matters not how corrupt, are to be exalted to heaven, to become as the angels of God. But still more emphatically are those making a covenant with death and an agreement with hell, who renounce the truths which Heaven has provided as a defense for the righteous in the day of trouble, and accept the refuge of lies offered by Satan in its stead—the delusive pretensions of spiritualism. GC 560.3"
"Because ye have said, We have made a covenant with death, and with hell are we at agreement; when the overflowing scourge shall pass through, it shall not come unto us: for we have made lies our refuge, and under falsehood have we hid ourselves:"
